89 2.5l running issue
hey all, my issue: 2.5l wrangler, fires up fine with a high idle, over 2000, immediately drops to around 800-1000 rpm, when i go to drive it, she starts bucking like its running out of gas and trying to stall. things ive checked: tps, map, crank sensors, fuel pressure, fuel filter, pickup screen, fuel pump 1 yr old but pressure is good, manifold temp sensor, cap n rotor, plugs, replaced to ignition control module as it tested bad at both autozone and discount. when i installed the new icm it ran great at an idle for about 5 mins then started acting up. if i let it stall and do not reset the key switch it will fire up fine for a few more minutes then start acting up again. starting to loose my patience and considering selling it to just be done with it, but i love my jeep. any thoughts? from what ive read there is no diagnostic on this thing and ive checked the sensors using voltage and ohm tests ive found on all the forums. thanks a bunch.
